Jay Bae created KAFKA-1357:
------------------------------

             Summary: Rack-aware replica assignment
                 Key: KAFKA-1357
                 URL: https://issues.apache.org/jira/browse/KAFKA-1357
             Project: Kafka
          Issue Type: Improvement
          Components: replication
            Reporter: Jay Bae
            Assignee: Neha Narkhede


Kafka in the cloud should be resilient to zone(rack in data center) outage. ElasticSearch is already doing replica assignment based on rack info, where replicas are not assigned to instances in the same rack.

We need this feature to make Kafka in AWS resilient in any zone outage. So far, I am doing manually get the broker information, write manual partition assignment json string and do manual assignment for the critical data source. It would be great rack-awareness replica assignment can be done automatically if the broker configuration has a rack info.
